Volume 150 of the series From Reason to Revolution 1721-1815 tells the story of the counter-revolutionary forces in English for the first time. Their origins, organisation, uniforms and fates are described in detail on the basis of primary documents, witness statements and recently discovered works of art, and illustrated with specially commissioned colour images. The French Revolution arose at a time when accepted norms within and between nations were stretched to breaking point. Nevertheless, there were Frenchmen who attempted to halt and even reverse the developing events. After being forced to seek refuge in neighbouring areas, they formed military units so that their resistance could become an armed counter-revolution. In some cases, this endeavour was short-lived; in others, it lasted more than a decade. Conventional historiography has largely ignored or marginalised this history. In French Émigré Armies of the Revolutionary Wars, the authors aim to provide military historians, enthusiasts, model makers and wargamers with a well-researched yet concise guide to these units. They also offer a nuanced account for general readers interested in the French Revolution. The first volume focuses on the Armée des Princes (17911792), while the second volume covers the Armée de Condé (17931801).
